Heroics class would always be the perfect place for UA students to show how they had grown. And no single class session was be more demonstrative of that growth than the one immediately following 1-A's internships.

"Holy crap!"

Saiki could only agree with Kirishima. Seeing Izuku's improvement as she pulled some incredible moves on the screen, he knew he wasn't the only one who levelled up. Evolved. That was a better word. If he wanted to be a hero he needed to live his gimmick to an extent.

Come to think of it, Izuku's movements as she darted about on top of the factory-like structure reminded him of a certain someone. A certain someone gritting her teeth, clenching her fists. Carefully he sidestepped towards her. "Hey, Katsumi, the way Izuku's moving. It's kind of like you, isn't it?"

"You better fuck off right now, creeper."

He laughed silently, stopping the recorder on his phone. That temper of hers was going to get her in trouble someday. Well, more trouble than earning punishments from him. He would just give her some space for now, save that little bit of leverage for later. Getting her ass plowed again. That sounded like a fitting punishment. He grinned in satisfaction, eyes returning to the big screen. It was fun to watch Izuku's jiggling but if she planned to move like that she'd need more support up top from her costume.

"Dude!" he heard a harsh whisper.

"Hm?"

Looking to his side he saw a blushing Jiro who couldn't quite meet his eyes. "You're showing!"

He was left momentarily confused. At least until he saw her eyes flick down, her cheeks flaring brighter as she looked away. Oh. "Right," he answered lowly. "Guess I'll need to get my costume adjusted." He grew down there since it was made. Not to mention his package was more powerful now. But to think he could still pitch a tent while wearing a dance belt. Damn thing probably tore.

"You're just gonna leave it there?!" Jiro whisper shouted at him as he continued to stand there unconcerned. "Are you that shameless?"

"It is what it is. It isn't going anywhere, especially if you keep blushing all bashful like that."

"Sh-shut up!" she growled, making the mistake of looking at him as she did. He smirked as he flexed a little down there causing his package to pulse. He got what he wanted as he saw her eyes get involuntarily drawn downwards. She covered her eyes but he could tell she was still looking through her fingers.

Rrrip

... Oops. He didn't need to look down to know his bulge had grown quite a bit more prominent due to his newest wardrobe malfunction.

"Oh my god."

"Yeah, really need to see about getting this fixed up," he nodded to himself, closing his eyes to focus his mind away from arousing thoughts. "... You're not making getting rid of it any easier, you know. I can feel your eyes on it."

"Right, sorr– I mean shut up, I wasn't looking at it."

Ice baths. Ice baths. That one wrinkly gym teacher who kept giving him shit for his quirk. Ice baths. Baseball. That super lame baseball hero playing baseball. Ice baths. He sighed. "There we go." He adjusted his stance out of relief. "You know a bunch of us are going to do some training at Momo's on Saturday if you want to come along."

"That's nice of her, letting a pervert like you in her house."

"Oh, so you're that type of girl," Saiki smirked to himself. "The type who says she's not interested while her eyes and hands tell a different story."

"I haven't put my hands on you."

Saiki shrugs. "I can be patient."

The hearing hero glared at the side of his head, causing his smirk to grow. "You know what? Yeah. I'd love to go. Need to make sure you don't try anything funny."

"Ha! Yeah. Okay. Whatever you need to tell yourself."

-(-)-

Saiki stared at the gate, looks left and right along the expanse of uniform fencing, what looked like woodland on the other side. "Was Momo so excited she gave me the address of a private park by accident?"

"I knew she was well off but this is... Wow," Jiro agreed, for once not looking quite so drowsy as she stared wide-eyed at the forest their class president's family seemed to own.

"We should probably..." Izuku trailed off, looking nervously at what looked like a security guard coming their way down the street. Three teenagers loitering in a rich neighbourhood wasn't a good look. She pushed the intercom button for just an instant–

"Saiki, is that you?!"

Jiro gave the only boy present a flat look. "First name basis, huh?"

"Sure, what's wrong with that Kyoka?" he grinned at her.

"I didn't give you permission to call me that."

"I'm more the type to ask forgiveness than– Pfft," he broke out into chuckles, "Nope. Can't even pretend." He didn't ask forgiveness.

"Uhh, Saiki..." Izuku got his attention, pointing to the guard still walking their way. Eyes focused on him alone.

He rolled his eyes. It figured. He leaned forward, tapping the intercom again. "Hey, Momo. I brought a couple of people with me like we talked about."

"Oh..." There was a hint of disappointment in her voice but she quickly recovered. "That's excellent! Please, come in everyone!" The gate swiftly opened automatically, allowing the students entrance.

The security guard laying his hand heavily on Saiki's shoulder was not so accommodating. "Is there a reason you three are bothering the Yaoyorozu?" he asked.

The reactions of the three to being accosted by security after being very clearly invited into the Yaoyorozu estate were varied. Izuku is confused. Saiki resigned. Jiro confrontational. "We were invited?" she said looking unimpressed, with a tone asking how he couldn't understand that. "We're Momo's classmates. Didn't you just hear her on the intercom?"

He made a show of looking over the three duffel bags they were carrying, then focused on Saiki again. "How about we all go together. Just for peace of mind." It wasn't a question. It wasn't a request.

Jiro's jaw hung. "You can't be serious!"

"They're always serious," Saiki grunted. "Fine. Let's not put a damper on Momo's day," he agreed with the guard, shrugging the man's hand off to start walking up the driveway. It wasn't like he had many options. He could throw a fit, make things even worse, lose the moral high ground. Or he could leave. Accomplishing nothing and Momo would still be let down.

"I don't get it," Izuku finally felt compelled to speak up. "Are security really this harsh here?"

"Come on Izuku, you know how it is," Saiki shrugged, "If you two were here alone this guy probably wouldn't care that much, at least after Momo invited you in. Meanwhile I'm... Well I'm sure a boy going to see the daughter of a wealthy family probably has something to do with it," he admitted, "But there's only one real reason." He looked at the guard still hovering over his shoulder.

"There's no reason to be aggressive, sir. We'll just go to the house and get all this cleared up."

The blue-haired boy rolled his eyes. "Aggressive. Right. My point is, I'm poor. This?" he tugged at the shoulder of his polo shirt that looked like it has seen better days. "This is the nicest outfit I own outside our school uniform and my work uniform. And it is just a sad state of affairs when you can call a fast food uniform your good clothes. But hey, UA tuition is expensive and I only receive enough money from my folks to stay alive. Guys like him?" he hooked a thumb at the guard, "They're trained to sniff out guys like me like they're bloodhounds. Isn't that right, watchdog?" No response. Well trained not to get taken in by bait. "People around these parts probably appreciate it. I get the feeling Momo won't. I'll say this much, she's a much better person than you'd ever expect from her upbringing. That says some good things about her family at least."

"Saiki," Jiro uttered, not prepared to learn this much about him. As well as not entirely comfortable with how judgemental he sounded of people he hadn't met. Even if given the circumstances it was understandable.

Izuku had already known some of it, but not to the extent that she had just heard.

Saiki himself wasn't big on the pity he heard in Jiro's voice. He cursed himself for letting his frustrations push him to spill his guts like that. But as he saw the house he pushed all of that aside. "Alright. Just try to act natural. Everything's fine. This asshole just made a minor mixup and will be leaving as soon as it gets cleared up! Isn't that right?" he asked, giving the two girls significant looks. "No classism here! Just a guard doing his job escorting some guests!" He paused. "Smile, Izuku."

"Ah, r-right!" she stammered, forcing a jagged, wooden smile onto her face.

"... Okay, I take it back, don't smile."

Another minute of walking. It turned out seeing the house didn't at all mean they were close to it. But as they reached the... Saiki wasn't sure what to call it. Front yard? They probably had to invent new terms to describe the geography of a home this big. But as they closed on the mansion's door Momo was there to greet them with a joyous smile. "Everyone! Welcome! I made sure to have some snacks prepared so we wouldn't start on an empty stomach! And– Mister Yasuo?" she asked, her smile turning to a small frown of confusion as she addressed the guard. "Is something wrong?"

"Everything's fine," Saiki answered before the guard could say anything. "He just offered to walk us up. I admit this place is so big I was worried about getting lost." He continued to smile as he looked at their 'escort'. "Isn't that right?"

"Really?" Momo asked, hand up to her mouth as she smiled again, "That's so nice of you Mister Yasuo! Thank you for helping my classmates feel welcome."

Yasuo looked to Miss Yaoyorozu, to the other two girls giving him thinly veiled looks of distaste, to the boy who had up until now been giving him a hard time. Who at this moment was telling him with his eyes to go along with this for Miss Yaoyorozu's sake. "... Yes ma'am, happy to be of service. I'll return to my patrol now."

"Thank you again, Mister Yasuo," she offered him a shallow bow as he turned and walked away.

And just like that the unfortunate interruption was away and dealt with to no longer weigh on the day, at least as far as Saiki was concerned. "I heard something about snacks?"

Momo clapped her hands with a bounce in her movements, "This way!" She happily led them into the dining hall where a small assortment of light, health-conscious snack options awaited them. A cheerful and light brunch later she led them into her personal training room.

"When I told my parents I wanted to be a hero when I grew up they spared no expense getting everything needed to train to be a fine hero!"

Saiki could tell. "They did their research," he noted, choosing to ignore the host's accidental bragging. "I recognise some of this stuff from Mirko's training space."

"Really?" Momo asked, excited at the prospect. He nodded. "That's wonderful to hear! It takes more than the right equipment, of course, but to know a respected pro trusts this equipment is reassuring!"

"Is that an olympic pool?!" Jiro pointed to the far end of the enormous space where the body of water in question sat on a lower level behind a glass partition.

Momo nodded eagerly, mistaking her friend's awe for excitement. "Swimming is wonderful full-body exercise, isn't it?! And so relaxing after more strenuous exercise! Did you bring a suit?"

"Uhh, no."

"I'm sure we can find you something later if we want to take a dip. In the meantime, shall we get started?"

-(-)-

Momo continued to be the most gracious of hosts all throughout the day. Doing her best to make sure everyone had everything they need, putting her own training on hold for that purpose. Something Saiki quickly put an end to once he realised. He did have ulterior motives for bringing Izuku (though Jiro was a spur of the moment decision), but wanting to train together was still always meant to be part of the equation. Training together.

"Are you both ready?" he asked. Momo and Izuku stood opposite one another in a decently large and empty space. "Remember, Izuku, down to about half power, okay? Momo is still getting used to using her quirk this way."

"Got it!"

"Go!"

Izuku moved in, slower than she was at the sports festival but still faster than baseline human speeds. She went in low, ducking down below what she could see of Momo's quirk going to work. The creation quirk seemed to be working to produce a blunted spear out of her right arm and a shield over her left. Her standard melee choices. But as Izuku attempted an early victory by staying out of the way of those hazards, she was quickly forced to sway right as a third creation, a rod of iron suddenly jutted out of Momo's right knee. Grabbing hold of it, Izuku tried to use the lever to unbalance her opponent but it came free without issue. Thinking quickly she brought the misshapen piece of metal up, forcing Momo to block with her shield. This left Izuku open to a counterattack from Momo's spear. Izuku's assault was halted in that moment, forcing the shorter girl onto the back foot.

"Did you really suggest this?" Jiro asked Saiki as the two watched the spar. "Momo's new fighting style?"

"I suggested she go back to the basics of her quirk," he answered, focusing mostly on the continuing bout, "And maybe a bit about the simple iron rods as an example. That's all though. I guess she took to my advice hard. She's already worked out some of the kinks. What Izuku tried, with grabbing the rod? I hadn't thought of that when I suggested it but she already has a counter to it." He smiled, proud for Momo's progress. "Izuku is the better fighter in skill and stats, but even so Momo is holding her own. All with the basic applications of her quirk. When she can combine this with the more complicated stuff she can make? She'll be devastating."

Jiro looked at him with new eyes, then sniffed a laugh. "You know when we first met I thought you were just an arrogant douche. Kind of like Todoroki. But I guess... You do have some good points."

His eyebrows raised as he glanced at her. Saw her earjacks twirling together as she looked just a little away from him. He smirked and returned his attention to the fight. "And on the first day I saw you, you flashed me your panties."

"You saw that?!"

"I didn't think you'd go for white, to be honest. But the kitten print was adorable."

"You're an asshole."

"And that's time!" Saiki announced loudly. Both the combatants stopped, breathing a little heavily. "How did it feel, Momo?"

She took a couple of panting breaths, but grinned widely. "It felt good! Though I worry I lose focus the longer a fight goes on. It got to the point she could anticipate my traps easily."

Izuku, shook her head, somehow looking equally pleased. "That's not it at all. I, ahh," she ran a hand through her hair. "I kind of got jittery after I almost got tagged by that knee. I tapped into more of my power without realising it. You weren't getting slower, I was getting faster. And you still kept up with me! You're amazing, Yaoyorozu!"

"Really?!" the rich girl practically glowed at the praise. "Thank you! And of course, you can call me Momo!"

"And you can call me Izuku!"

Saiki watched with secret satisfaction. Mission success.

He came to a realisation somewhere between round seventeen and eighty-seven with Mirko (that whole period had kind of blurred together after a while). Tormenting Katsumi with contests and punishment games was all well and good. She was prideful enough to go along with that for the rest of her damn life. Having bun fun with Mirko... Well he didn't really understand why that was so easy to maintain but the text on his phone asking if he was still coming over tomorrow told him he was in no danger of failing there.

Izuku and Momo? They were... Different. He didn't want to trick or cheat or coerce them into anything with him. Maybe it was because Momo was the one genuinely good person he'd found born in her circumstances. Maybe it was because Izuku was so much like him, having to scrape for every advantage and still finding victory. Maybe it was because when he looks back on his interactions with them, he couldn't quite bring himself to believe any of them were manipulations. He wanted Katsumi because she got him hard. The same for Mirko. The same for Juri when he was with her. Well... More because she got him off in the last case. Juri was fine for what she was and that was it.

But these two. Or even these three as he glanced at Jiro still stewing over his teasing her. He wanted them. As more than just sexual outlets. Momo and Izuku, he just plain liked being around them.

And so... If he didn't want to sacrifice anything. Didn't want to lose either of them, then they couldn't be rivals for his affections, or at least not just that. They needed to like being around each other. And so today was necessary. The rivalry that started at the sports festival needed to be evolved to a level of mutual respect and admiration. A relationship he could slot himself into.

"Oh my!" Momo gasped, "It's getting rather late!" she realised as she looks out the window to see the setting sun. "Perhaps a quick swim to cool off and we shall call an end for today?"

"I mean, I still don't have a suit," Jiro reminded the host.

"Neither do I," Izuku admitted sheepishly.

The three girls looked to the only boy. "What?" he asked. "I brought one. Why wouldn't I?" He hadn't known Momo was this rich but he knew she was wealthy enough that slipping his swim trunks into his duffel wasn't a ridiculous choice.

"Well, not to worry," Momo assured the less prepared. "While I was arranging lunch I made sure to arrange some suits for everyone also! They're in the changing room."

Izuku exchanged a confused look with Jiro. "How do you know our sizes?" she asked.

"Oh as part of training for my quirk I learned to estimate dimensions fairly accurately. They won't be perfect but they'll fit," she assured.

Jiro shifted, feeling awkward. "Well... Since you went to all that trouble..."

"Oh, it was no trouble at all! Come on, come on, girls first!" Momo insisted, using her exuberance to usher the girls into the changing room.

Saiki was left to his own devices for... Quite some time. Longer than he would have expected it to take for the girls to change into swimwear. He got a somewhat satisfying answer to the question of why when two of the girls came out in two piece suits, both blushing brightly as they emerged. "Wow," he said with an appreciative look up and down. That look was almost enough to send Izuku's blush all the way up to her hairline.

"I would have preferred a one piece," Jiro managed to say through her embarrassment, unsure exactly what part of herself she wanted to cover up. The result, her arms doing a bizarre dance.

"I don't know about that. That suit really works for you," Saiki praises honestly. It wasn't even entirely lecherous from seeing that much skin. It really did suit her well.

"Shut up!"

Dong!

"What was that?" Jiro asked. "Sounded like... A bell?"

"Don't worry about it."

"I-it's y-your turn Saiki," Izuku stammered, making stiff movements away from the changing room door.

"Really? Isn't Momo still in there?"

"She said she wanted to get the nice towels for us."

"Yeah, that sounds like her." He grabbed his duffel and walked past the two girls, resisting the urge to pinch Jiro's cute little butt. Dumping his bag inside he quickly grabbed his swim trunks and started to strip off his sweaty gym clothes, setting them to one side. Near nude, he looked down at the jock he had to wear at all times and sighed. At least it doubled as a cup. And the fact that was there because without it his cock could quite literally burst out of his pants was a nice salve for his pride, injured for having to wear something so silly. A metal jock strap. He could feel the erection caused by Jiro's bashfulness straining against the metal. Uncomfortable but not painful.

Unlike the girls, it only took him about a minute total to change into his trunks at a leisurely pace. As he put his bag up on a shelf he heard a knock on the door. Not from the workout room side, form the other door that led to the rest of the house. "Yeah?"

"Are you decent?" he heard Momo's voice through the door.

"Yeah, you're good." She entered, all confidence despite her somewhat revealing attire. A scarlet bikini that shows a lot more skin than Jiro's. "Wow. You know to be honest I expected a sling given your hero costume– Woah!" he yelped as she kept walking, pushing him against the changing room wall.

"You lied to me," she accused, only to then pull his head down to lock her lips with his.

"Mmh?" he asked, but quickly stopped caring what she was talking about as he deepened the kiss, her soft body pressing up against his chest.

The kiss lasted only a few seconds longer before Momo pulled away, breathy, frustrated. She looked away from him. "Kyoka told me what happened with Mister Yasuo."

Suddenly the kiss tasted bitter on his tongue. "She shouldn't have done that."

"I'm glad she did," Momo countered, her fingers trailing against his chest. "She was angry and so am I. I know why you did it. You knew I was looking forward to today and you didn't want something like this to spoil it. But the fact that you were treated like that by someone acting for my sake, it hurts. And the chance to make sure it never happens again is more important to me than having a perfectly carefree day." Her hand reached out to cup his cheek. "It makes me happy that you care so much for my feelings, but please let me care for yours."

His thoughts from only a few minutes ago. They were reinforced a thousand times by those words. He swallowed thickly. He couldn't remember anyone ever expressing that kind of care for him. Never in a way that made him believe it. "I... That might take some adjustment."

"Then we'll adjust." She took him by the hand and pulled him towards the workout room door...

Only for Saiki to stop her short. "Uh, they probably shouldn't know we were in here together."

Her eyes widened. "Oh." She honestly hadn't considered that. "Yes. Of course. I'll just come through in a minute."

"With towels," he reminded her.

"Right! Towels! I'll be back momentarily!"
